    OK, this most likely is an inefficient solution. I store the galaxies as a list of [x, y], apply offset to their coordinates one by one depending on how many lines/columns with smaller indexes there are, then use itertools.combinations to find pairs and finally calculate Manhattan distances between the pairs. That's a lot of overhead that includes over 100 000 pairs in the combinations iterator, though it works pretty quickly.

    Anyway, after noticing that the sequences in the input are not arithmetic, I decided not to look for any fancy solutions. I initially went for lists and solved both parts instantly, but then I decided to do it more properly, so hello, deques.

    You know what? Getting my rear kicked every year since 2018 pays off. I may have given up on day 15 of AoC 2019, but I did learn something. That's why about 10 minutes into my naive approach's fantastillion iteration, I recalled the Jupiter moons puzzle. As soon as I saw that this approach would work for the test data, it felt good. So to solve part 2, I just needed to look up a nice lcm-of-a-list formula.

    This solution is probably a great example of 'how not to do it'. Overengineered in some parts, just plain dumb-hardcoded in others, but I spent so much time debugging without realizing that I misunderstood the rules that I pretty much stopped caring.

    Implementic quadratic formulas felt like day 1. Not the most elegant solution, but after yesterday, I'll take it.
